STOCKLESS ANCHOR.

To all whom it may concern:

Be it known that I, WAL'rnn'Soo'rr Bron LEY, citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Stockless Anchors, of which the following is a specification.

My invention relates to stockless anchors and resides in an anchor of that type which can be readily made of cast steel, with a minimum of machine operations, and with a cooperation between shank and crown which is both cheap in construction and of great strength.

My invention resides in the features hereinafter described. and pointed out in the claims.

For an illustration of my invention, reference may he had to the accompanying drawing, in which:

Figure 1 is a front elevation, partly in section. Fig. 2 isa side elevation, partly. in section.

The shank 1 has at its lower end the integral head 2 having the beveled or conical portion 3, a being the lower face of the head, and 5 the vertical sides. 4

The flukes 6 are cast integral with the crown 7, the crown being provided with integral downwardly extending lugs 8, 8. An elongated transverse openin 9 on the iiuke side of the crown permits the shank 1 to swing from side to side with respect to the crown, as will appear from Fig. 2.

In the bottom or under side of the crown, there is formed a cavity between the lugs 8, saidcavity communicating with the transverse opening 9, and provided with inclined or conical walls 10 to form a bearing for the portion 3 of the shankhead. The socket cavity thus extends entirely through the crown and has a wide mouthed. opening at the underside of the crown.

The shank is slipped in from the bottom through the cavity between the lugs S and I up through the crown to the position shown in the drawings. A bolt or pin is then passed through the lugs 8 and secured, thus Specification of Letters Patent.

Application filed October 6, '1904. Serial No. 227,417.

preventing the shank from separating fronr material which would. work into the cavity and clog the anchor if such cavity were closed.

What I claim is:

l. A stockless anchor comprising the 00111-- bination with a single crown piece having integral flukes, of a shank, a head thereon, the upper portion of said head having conical bearing surfaces, a socket in said crown piece, the fluke side of said socket being conical to receive said conical bearing surfaces on said head, a permanently open cavity communicating with said socket, an opening from said socket to the fluke side of said crown piece to receive said. shank, and means in said permanently open cavity for preventing said shank from separating from said crown piece.

2. A stockless anchor comprising the combination with a single crown piece having integral flakes, of a shank, a conical head thereon, a cavity extending entirely through said crown and having wide mouthed openingat the underside of said crown, the bottom of said cavity formed by conical surfaces-adapted to receive said conical head, whereby said head bears directly upon said crown piece and whereby the parts are open to the sea, and means for preventing said shank from separating from said crown piece.

In testimony whereof I aiiix my signature in presence of two witnesses.
